I have zipped up a ZM RPM along with a couple of perl mods needed and put them here:
http://www.elltel.net/melins/mdv_2006/
To use them on 2006 you will need to configure ftp sources for main, contrib, plf_free, and plf_nonfree.
Mandriva 2006 comes with several choices for apache,MySQL, and php versions. I have my system set up with apache-mpm-prefork-2.0.54, MySQL-Max-4.1.12, and php-5.0.4
Once you have Mandriva and the rest of the LAMP stack installed and your ftp sources configured you can install ZM using urpmi and it will work out and install any missing packages. Just inzip the tarball and do "urpmi *.rpm" from the same directory.
Have fun,
